Description: | Specimen of a fossil brachiopod (lamp shell), Harknesella vespertilio Sowerby, collected from unspecified rocks of Middle Ordovician, Caradoc age from Grafton (?), Shropshire (Midland England).
There are many different kinds of brachiopod (lamp shell) fossils in this siltstone. This suggests that many brachiopods lived and died over a period of time and their shells formed an important part of the sediment deposited on the seabed. The largest fan-shaped shell (towards the left side of the rock) is called Harknesella. At some time after the brachiopods had become fossilised, their shells were dissolved away so that their impressions (moulds) are all that remain in the rock.
The specimen was found in Shropshire.
It is from the Ordovician period (495 - 443 million years ago) | Publisher: | Tyne & Wear Archives & Museums | Subjects: | Classification: Animalia Brachiopoda Invertebrata Articulata | Temporal: | Ordovician period (495 - 443 million years ago) | Source: | Tyne & Wear Archives & Museums | Identifier: | http://www.twmuseums.org.uk/geofinder/se... | Go to resource |
